CUSTOMIZATION

1. Implementation Parameters:

   • The implementation requires two template parameters to control the input complex type and the distance matrix implementation to be used.
   • Sample implementations can be found in criticalCells.hpp files in the form of structs.

2. Customization Process:

   • Customization can be achieved by specializing predefined functions.
   • The DistMat must provide a distance function to obtain the distance between two indices.

3. Custom Complex Handling:

   • If a custom complex is used, there are two options:
     • Store the current simplex in the simplex field and implement the next_simplex function for seeking.
     • Provide a custom implementation, such as:

       std::map<double, std::vector<std::vector<int>>> binEdgeSimplexes();                                                                        
       std::map<double, std::vector<std::vector<int>>> dsimplices_batches(ComplexType &simplex_const, size_t dim, size_t batch_size);

   • These functions are crucial for handling custom complex types and ensuring proper functionality.
